To all whom it may concern: 7 1

Be it known that l, KARL BoMHAnD, a citizen of the German Republic,residing at Munich, Germany, have invented certain new and usefulImprovements in Vaginal Syringes, of which thefollowing isa-specification. V This invention has reference to improvements invaginal irrigating syringes and relates more specifically toadevice ofthe return-flow character, in which the cleansing or medicinal fluid is'introduced'at the front end of the'vaginaand is withdrawn againtherefrom at the innermost portion after having been in intimate contactwith the entire surface of the vagina, special means being provided toprevent the flesh folds from occluding the outlet orifice of thesyringe, which would prevent the fluid from running off.

any suitable material, preferably hard glass, can readily be taken apartfor cleaning purposes and, as there are no valves or other movableparts, it is not liable to get out of order.

- My invention will best be understood from the accompanying'drawing, inwhich Fig.

1 shows a side elevation, partly: insection, of the new syringe; Fig."2, is a section on line 22 of Fig. 1, and Fig. 3 showsdia grammaticallyhow the syringe is connected in use with the supply and wastereceptacles respectively. f V

The device essentially comprises the outer inflow or mantle member 1from whichilaterally communicatingly extends the nipple branch member 2,and the outflow member 3 arranged within the member 1 with capability ofrelative axial and rotary displacement. The inflow member 1 iscontracted at its one end, as at 4, and it is provided at its other endwith inwardly directed interspaced projections 5, obtained bycorrespondingly depressin the tubewall to provlde seating recesses orthethickened rim 6 of a bell-shaped cuff or shield 7 of suitable material,preferably soft rubber, designed to occlude the mouth of the vagina forpreventing leakage therefrom of the douching fluid.

I may also see fit to dispense with such a formed between the two nestedtubes 1 and '3 by the knobs 5 into the vagina and is separate occluderand integrally form the tube end into proper bell shape, though,,obviously, the yieldable rubber cufi would generally be preferred.

Anelectrode 10 may be provided in the tube with the snugly nested tube 3by meansof 1 for introducing electrical currents of dif- Iferentcharacter, as well known in the respective arts.

In use the tube 3 is inserted into the vagina with the rubber cufftightly closing V the entrance thereof, the branch tube 2 beingconnectedby tubing 12 with the tankll. I

It the waste receptacle 13 is held in the relative position I, thedischarge flow will be less accentuated than with the receptacle inposition II, it being understood that the outlet end of tube 3 isconnected to the receptacle 13 by tubing '14. As there is no internalpressure to overcome, owing to the complete absence of air pockets or;other resistance, the whole system thus being at all times underatmospheric pressure, any change in the relative position ofthe-receptacles will only. alter the rategof flow of the liquid. It isthus possible by positioning supply tank, waste tank and syringe onpractically the same level to retain the liquid stationary within thevagina for any desired period.

Though I have described and shown the new deviceras introducing thedouche fluid through the outer member and withdrawing it again throughthe inner member, I want it to beparticularly understood that I can justas well cause. the fluid to flow in reverse direction, that is to say, Ican introduce it through the inner member and run it oif again throughtheoutermember, without in any way interfering with the underlyingtheoretical considerations or afl'ecting the specific construction ofthe device. I am, however, satisfied that to reverse the flow of theirrigating fluid will, to some extent, lower the efliciency of theoperation, and for this reason I ham-specifically described the moreefficient procedure.
